ABSTRACT
BACKGROUND:
The use of video laryngoscopes by novice physicians may improve first-pass success rates compared with direct laryngoscopy.OBJECTIVE:
The aim of the present study was to assess whether time to intubation, number of laryngoscopy attempts, and first-pass success rate during laryngoscopy with the video laryngoscope or conventional Macintosh laryngoscope are affected by personal protective equipment (PPE) donning.METHODS:
Seventy inexperienced physicians were randomly assigned to video laryngoscope or Macintosh groups and were instructed to perform intubation with both devices on a manikin, using PPE or a standard uniform. The primary outcomes were insertion time, number of laryngoscopy attempts, and first-pass success rates for each device with or without donning PPE.RESULTS:
In the Macintosh group, significantly less time was needed for the first successful intubation without PPE vs. with PPE (12.17 ± 3.69 s vs. 24.07 ± 5.09 s, respectively; p < 0.0001). On the other hand, such difference was not observed in the video laryngoscope group (14.99 ± 3.01 s vs. 14.01 ± 3.35 s, respectively; p = 0.07). With PPE, the first-pass success rate was significantly higher in the video laryngoscope group [41 (58.6%) vs. 66 (94.3%), p < 0.001]. The use of the video laryngoscope resulted in a significant decrease in insertion time compared with the Macintosh blade (14.01 ± 3.35 s vs. 24.07 ± 5.09 s, respectively; p < 0.0001).CONCLUSION:
First-pass success and insertion time with the video laryngoscope were not affected by PPE donning. However, both were negatively affected with the Macintosh laryngoscope.Keywords
